ALBERT B. HOLLEY-, F VIRGINIA,v MINNESOTA CONVEYER LOADER.

Specification of Letters Patent. Patented Feb, 28, .1922.

Application led September 8, 1920.` Serial No. 468,827.

To all whom t may concern.'

Be it known that I, ALBERT B.'IIOLLEY, a citizen of the United 'States of America, residing at Virginia, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Cony veyer Loaders, of which the following is a specification.

My present invention relates generally to conveyer-loaders, and more particularly to an apparatus of the general character, and operating along the lines, of my Patent 1,280,032 dated September 24, 1918, wherein the material of whatever its nature is conveyed by rocking movements of a conveyer trough having in its swing a rearward conveying movement during which the material moves with the conveyer, and a forward accelerated movement during which the material falls but is relatively stationary in so far as lengthwise movement of the trough.'

As compared with my patent above referred to,l my present invention embodies considerable operating advantage in respect to more ready portability, greater range of adjustment and consequently of use, and is in many other respects more convenient, useful and practical, and it is the bringing about of these improvements and advantages that my present invention aims.

Referring to the accompanying drawings, which illustrate the improvements and form a part of this specification,

Figure 1 is a side elevation of the complete machine,

Figure 2 is a top plan view thereof,

Figure 3 is a rear elevation,

Figure 4 is an enlarged view, partly in elevation and partly in-section, of the adjacent portions of the two conveyer troughs, showing their connections,

Figure 5 is an enlarged side view of the lower end of the main trough,

Figure 6 is a front 'elevation .of the parts shown in Figure 5. v

In Figures 1 and 3 in particular I have shown a tractor 10, including caterpillar treads 11 and having thereon an internal combustion or other motor 12, and while I have thus shown a tractor of somewhat definite type, it is to be understood thatot-her types may be readily employed..

Inclinedv forwardly and downwardly with its upper read end above the tractor 10 is the conveyer frame 13 whose said upper portion supports a super-structure or motor` platform 14 and whose forwardly and downwardly inclined sides 15- are rigidly connected and support at their extreme lower` 'endsforwardly projecting guides 158L disposed in angular relation thereto and approXimately parallel with the surface on which the tractor travels, for a purpose which A will be presently described. The upper portion of frame13 is supported in vertically spaced relation above tractor 10, upon the upper end of a king ost 16 journaled vertically in the tractor rame, so that the con` veyer frame l is thus capable of assuming various angular positions with respect to the tractor as seen by a comparison of the full y and dotted'lines of Figure 2.

Within the conveyer frame 13 and inclined substantially in parallelism therewith between its sides 15, is the main elevating conveyer trough 17, whose lower end has a hinged extension lip 18 yieldingly engaging the upper surface of the relatively movable digger 19, and whose support is accomplished by bell-cranks 20 and 21 respectively' at the upper and lower sides of the trough. The upper .ends of these levers 20 and 21 have bearings on the frame sides 15, and the lower ends of the lower levers 21 are pivotally connected at 22 with the forward ends of links 23. These links connect at their rear ends by pivots 24 with the upper ends of bell-cranks 25 fulcrumed in the lower portions of the frame sides 15 as best seen in Figures 5 and 6, and the lower ends of bellcranks 25 connect by forwardly extending links`26 with tubular side portions of the digger 19 slidably disposed on' the beforementioned guides 15a. It thus becomes evident that upward and downward lengthwise swinging movements of the trough 17 will be communicated to the digger 19 in similar directions and to a somewhat greater extent, making one move differentially with respect to the other.

The upper bell-cranks 20 are connected at their upper ends to rigid arms 27 and these arms are in turn connected by forwardly and upwardly inclined links 28 with the rigid arms 29 of a cam shaftBO, the latter passing through a cam housing 31 wherein cams of the naturedescribed in my patent above, or any other suitable nature, act to oscillate shaft 30 in 'order to swing the trough 17 lengthwise in uniform rearward motions and 110 accelerated return motions. 1 The cams used `for this purpose are actuated through a receive and maintain the shaft 32 from a suitable motor 33 on the motor platform 14, the latter of which has a rearwardly extending portion 34 supporting the upper central pivot 35a of a rectangular upright and transversely disposed frame 35 having ,a lower hollow pivot 36 in a rearwardly extending portion 37 of the main frame 13.

At the lower side portions .of upright frame 35, which latter swivels angularly on its upper and lower pivots 35a and 36, arethe pivots 38 of a second trough frame 39 which extends rearwardly from the main frame and is permitted to swing vertically on its pivots 38. Frame 39 is supported by means of rearwardly and downwardly inclined side hangers 40 whose rear ends are pivoted v"to the sides of frame 39 at 41, and whose forward ends have lengthwise series of apertures 42 providing for adjustable connection with the upper side portions of frame 35.

Suspended in the rear trough frame 39, with its forward receiving end beneath the overlapping vertically spaced rear discharging end of the main conveying trough, is a rear trough 43 whose rear end projects rearwardly of the tractor frame so as to provide the necessary underneath clearance for wagons, cars and the like into which said rear end of the rear trough is intended to discharge in use. Trough 43 is suspended in trough frame 39 by pivoted suspension hangers 44 and this trough is thus free to Same operating movements before described in connection with the forward inclined trough 17.

ovement is communicated from trough 17 to trough 43 by connections leading from the upper bell-cranks 20 of the former, hav ing links 45 extending rearwardly therefrom and connected to the ends of a cross shaft 46. At its center, cross shaft 46 has pivoted thereto one arm of a bell-crank 47,

the other arm of which is pivoted to the up.

per forward end of a rearwardly and downwardly inclined link 48, as most clearly shown in Figure 4. The lower rear end of link 48 connects pivotally with the forward end of a bell-crank 49 fulcrumed beneath the` rear extension 37 of the main frame and the rear armof which is universally jointed at 50 with the lower end of a connecting rod 51 extending upwardly through the hollow lower pivot 36 of frame 35. The upper end' of rod 51 is universally jointed at 52 with one end of a bell-crank 53 whose opposite end is pivoted to the trough 43 in about the line of the pivots 38 on which the trough frame may be shifted vertically;

It is thusobvious that during the uniform rearward 'material shifting movements of trough `17, similar movements will be imparted to trough 43, likewise accelerating forward movements, and that these movements will be in the same direction and will bring about uniform step by step rearward and upward movement of the material along the trough 17, from the rear end of this troughto the forward end of trough 43 ,and finally from the rear discharged end of this latter trough into wagons, cars and the like, to effectively clear which the rear end of the'rear trough can be swung vertically.

The entire conveyer frame can swivel angularly on the king post journaled vertically in the tractor frame, and in addition to this, the rear trough and its frame can swivel to the angular positions shown in dotted lines in Figure 2 independent of the forward main trough and its frame.

In operation, the tractor advances the entire apparatus as this becomes necessary, and in order to avoid entiredependence of the king post, I provide an arrangement by which the tractor pushes against the lower forward portion of the main trough frame and at the same time permits the latter to be turned with respect thereto. For this purpose the tractor has horizontal side bars 54 rigidly supporting at their forward ends 'a segmental push bar 55. The forward surface of this bar 55 is engaged by the rear rollers 56 of an adjustable bracket 57 suspended by a pivoted hanger 58 from the frame 13 and connected by an oppositely threaded adjusting screw 59, having a hand wheel 60, with .a beam 6l pivotally attached to the lower forward portion of frame 13. By turning hand wheel 60 the lower forward end of the conveyer trough 17 and also its digger 19 may be`adjusted vertically so as to compensate, for instance, for inequalities of the ground over which the tractor may be travelling or positioned.

It is obvious from the foregoing that my invention provides a readily portable machine 'of its character capable of continuous effective and speedy operation as well .as one which will be particularly efficient in loading, and evenly loading, wagons, cars and the like from end to end withoutV angular shifting of the main frame. It is also 4obviousthat by virtue of the relatively movable digger, the digging operation ywill be especially effective and advantageous along with the other improvements over my prior patent of which previous mention has been made.
